摘要： PURPOSE:To quicken the reversion of a rotary drum by fitting an arm wherein a pad is fitted to the upper part in both sides of a barrel part of the rotary drum so that the arm is capable of slanting in a prescribed length and angle in the central direction and in the length direction of the rotary drum. CONSTITUTION:A rotary drum 15 in which plural kinds of powdery materials are introduced is driven and rotated by the friction wheels 7, 7' rotating with a motor 9. Simultaneously a bed plate 1 is rocked like a seesaw by a crank mechanism 11. Therefore the powdery materials in the rotary drum 15 are scraped up by a scraping plate and mixed and also the mixing degree is increased by transferring the powdery materials in the inside of the rotary drum 15 from the front part to the rear part and reversely from the rear part to the front part by means of the bed plate 1.

摘要： PURPOSE:To enable manufacture of a resin mold coil having good electric insulation properties and mechanical strength by forming an interlayer insulation so that the resin impregnated in glass roving material may infiltrate enough. CONSTITUTION:Every time a wound conductor layer 7 is formed by winding a coil conductor 6 for one layer, the insulating layers B1 and B3 which are formed by winding a glass roving material 3 impregnated with heat-curable resin 5 thickly for the part of high interlayer voltage and thinly for the part of low interlayer voltage in parallel with forming plural layers or with an inclination are interposed, and a slanted layer B2 formed by winding the glass roving material 3 impregnated with said resin 5 helically is arranged between said insulating layers B1 and B3, thereby constituting a naked coil 10. Then, this naked coil 10 is heated while being rotated so as to harden the resin 5 impregnated in the glass roving material 3. Thus, the resin mold coil having good electrical insulation properties and mechanical strength can be fabricated.

摘要： PURPOSE:To enable to use an element of small withstand voltage by limiting an inverter current in a high speed overcurrent limiter when a load current exceeds a set level, and controlling a chopper circuit by a low speed overcurrent limiter. CONSTITUTION:A chopper circuit 3 for controlling a pulse width modulation controller 5 is connected to a rectifier 2, a brushless motor 7 is connected through an inverter 6, and a signal from a Hall element H is applied to a distributor 8 and a drive circuit 9 to control the inverter 6. A load current is detected by a resistor RL, an inverter output current is limited through a high speed overcurrent limiter 10 when exceeding approx. 200% of the rated value, and the chopper circuit 3 is controlled through a low speed overcurrent limiter 11 and a priority circuit 12. Accordingly, the peak value is suppressed at a high speed, and limited to the prescribed level, thereby enabling to use an element of small withstand voltage.
